Best Video Upscaler in 2026: Free & Paid Tools Compared

The best video upscaler depends on the job. For a short clip you want to fix without installing anything, use an online AI video upscaler. For long projects or batches, desktop software such as Topaz Video gives you more control. If you already edit in DaVinci Resolve Studio, its Super Scale feature keeps upscaling inside the edit. If you want a free option and can handle some setup, the open-source Video2X runs on your own GPU.

What makes a good video upscaler

• Stable detail between frames. An upscaler that treats every frame as a separate image can make each frame sharper and the video worse, because the invented texture changes from frame to frame and flickers. Judge a moving shot, not a paused frame.
• Faithful rather than dramatic detail. AI upscaling estimates detail. Faces that turn waxy, changed lettering or halos around edges mean the model is inventing too much.
• Limits that fit your footage. Check accepted formats, maximum length and file size before you prepare a project, not after.
• The cost of a finished export. Compare what a complete clip at your target resolution costs, including trial restrictions and watermarks, rather than a headline price.

1. VideoEnhancer: an online AI video upscaler for short clips

Our AI video upscaler runs FlashVSR, a one-step diffusion model for video super-resolution, on our servers. Upload an MP4 of up to 500 MB and 120 seconds, choose 1080p, 2K or 4K and download the result. The first 5 seconds are a free trial. Paid processing costs $0.03 per input second at 1080p, $0.06 at 2K and $0.10 at 4K, so a 30-second clip at 4K is $3.00. Output has no watermark and stays downloadable for 3 days.

Not a fit if: your footage runs longer than 120 seconds and you do not want to split it, you need batch processing or frame-rate conversion, or you cannot upload the file to a third-party service.

2. Topaz Video: desktop upscaling with more control

Topaz Video is dedicated desktop software for upscaling and enhancement, with several models and manual controls. It suits people who process a lot of footage or long files and have a capable GPU. Check the current license terms, hardware requirements and any cloud-rendering options before buying, and test the same moving clip you would test elsewhere.

3. DaVinci Resolve Studio: upscale inside your edit

DaVinci Resolve is an editor first. Its Studio edition includes Super Scale for higher-quality upscaling of clips placed on a larger timeline; the free edition does not. It makes most sense when the upscale is one step in a project you are already cutting, grading and exporting in Resolve.

4. Video2X: a free, open-source video upscaler

Video2X is an open-source tool that runs upscaling models such as Real-ESRGAN and Anime4K locally. It costs nothing and your footage never leaves your computer. In exchange you handle installation, model choice and settings, speed depends on your GPU, and image models applied frame by frame can flicker on live-action footage. Test motion carefully.

5. CapCut: quick enhancement while editing

CapCut puts enhancement tools inside a popular editor for short social videos. It is convenient when you are already editing there. Check which enhancement features your plan includes, the export resolution you actually get and the account terms before relying on it for client work.

6. TensorPix: another online option

TensorPix is another browser-based enhancement service. Compare its supported files, trial restrictions and the cost of a completed export with other online options, and include upload and download time for large files.

Which video upscaler should you choose?

Your situation	Start with
One short clip, no software, no GPU	An online AI video upscaler such as VideoEnhancer
Long videos or regular batch work	Desktop software such as Topaz Video
Already editing and grading in Resolve	DaVinci Resolve Studio Super Scale
Zero budget and comfortable with setup	Video2X
Short social edit on a phone	Your editor's built-in tools, then check the export
Old VHS or camcorder capture	A restoration workflow first; see video restoration tools

How to compare video upscalers fairly

1. Pick one 5 to 10-second clip with a face, some fine texture, small text and camera or subject movement.
2. Run it through each tool at the same output resolution.
3. Compare the results with the original at the same display size, then play them at normal speed.
4. Look for flicker, waxy skin, halos, changed lettering and audio drift.
5. Write down what the full-length export would cost in each tool, including any trial limits.

Frequently asked questions

What is the best free video upscaler?

Fully free AI upscaling usually means open-source software such as Video2X running on your own GPU. Online upscalers typically offer a limited trial instead: ours covers 5 seconds, then processing is paid. If your clip is already sharp and only needs a bigger frame, resizing in a free editor is enough.

What is the best AI video upscaler for 4K?

The one that keeps your footage stable at 4K, which depends on the source more than the tool. A clean 1080p file has room to benefit; 480p footage usually looks better stopped at 1080p. Our guide to upscaling video to 4K explains how to decide.

Is an online video upscaler as good as desktop software?

There is no general answer, because quality depends on the model and your footage. Online tools win on convenience and need no hardware; desktop tools win on length limits, batch work and control. Test the same clip in both.
